H112PC

SCGC™ HDPE H112PC is a black high density polyethylene compound producing from high selective catalyst in the precise process control system, bimodal technology. SCGC™ HDPE H112PC is classified as MRS 11.2 material (PE112). It provides superior long-term hydrostatic strength balancing with high slow crack growth and rapid crack propagation resistance. It has been designed for better safety factor in long-term use. Besides that, it can be produced in all ranges of pipe diameters, especially recommended for the production of very thick wall and large diameter pipe.
